为了了解错偏量对厚板45°斜交对接焊缝的受力影响,采用有限元方法建立了该部位的实体有限元模型,对无错偏加工条件下和考虑错偏影响的对接焊缝进行对比分析,分别计算了在弯矩和轴力作用下焊缝附近的应力分布规律,并将有限元结果和理论值进行比较。结果表明,板件间错偏量会使焊缝附近受力更为不利,且随着焊缝错偏量的增加,应力绝对值变大,其中轴力作用下的影响比弯矩作用下的影响大。
In order to understand the effect of offsetting bias on the force of 45 ° diagonal butt weld, the finite element method was used to establish the solid finite element model of this part. For butt welds The comparative analysis is carried out. The stress distribution around the weld seam under the action of bending moment and axial force are calculated, and the result of the finite element method is compared with the theoretical value. The results show that the misalignment between plates will make the stress in the vicinity of the weld more unfavorable, and the absolute value of stress increases with the increase of the misalignment of the weld. The influence of axial force is stronger than that of the bending moment Great impact.
